i was wondering if i am getting the whole process of the RGH right
i would greatly appreciate if someone corrects what i think goes on during the RGH process
we have 6 wires for Phat ,
1- power
2- GND
3- standby-clk : Continuous clocking from XBOX--> CR
4- post-out: signal from XBOX--> CR, momentarily at some specific time indicating that the kernel is at some point suitable to start sending the glitching signal (right Huh?)
5- pll_bypass: signal from CR---> XBOX to slowdown the processor so the reset/glitch signal can hit some specific time during kernel launching (is it continuous???)
6- cpu_reset : the actual reset signal (momentarily and indicated by the debug led at the CR, right Huh??)

so if the CR is blinking green at 5 sec. intervals, then standby_clk, post_out are fine
and either the cpu is not slowed (cpu_pll_bypass problem) or the cpu reset is not reaching the processor (physical or interference)

so again please correct me if i am wrong

The LED is on when the CPU is slowed Down. The bootprocess reaches a "Special" State. Then pll_bypass is asserted an the LED is on. So you can say the LED is equal to pll_bypass. Cpu_rst is asserted After a Timer reaches a specific value for x stb_clk cycles. I hope you understand what i want to say :-)
